Technical Field

[0001] The utility model relates to the field of lightweight steel wheels, in particular to a lightweight steel wheel. Background Art

[0002] In order to reduce vehicle load and increase speed, steel wheels for high-speed engineering vehicles, mobile cranes, fire trucks, military off-road vehicles, etc. need to use lightweight steel wheels. Among them, the "lightweight split heavy-load steel wheel" disclosed in the application number "CN202020556938.2" is also an increasingly mature technology. Its "unique design of the inner rim and the outer rim enhances the structural strength and reduces the weight, making the heavy-loaded steel wheel of more than 70 kg reduced to 45 kg". However, the wheel still has the following defects during use: the steel wheel can indeed enhance the structural strength and reduce the weight through the unique design of the inner rim and the outer rim, but the structure of the inner rim and the outer rim is simple. Therefore, while reducing the counterweight, the structural strength of itself needs to be improved. Based on this, it is necessary to provide a wheel that can significantly enhance the strength of the wheel while taking into account lightweight. Utility Model Content
